Two that ship today:</p> <ul> <li> <strong>Timestamp Converter</strong> — two-way conversion between seconds, milliseconds, local time and UTC, with automatic <code>s</code>/<code>ms</code> unit detection. No more guessing whether <code>1700000000</code> is seconds or milliseconds.</li> <li> <strong>JSON Parser</strong> — prettify, minify, and pinpoint the exact location of common JSON errors instead of staring at "Unexpected token at position 4172".</li> </ul> <p>No ads. No bloat. Open contribution.</p> <h2> Why it's different </h2> <p>Most "free online tools" monetize <em>you</em>. OpenNomos flips the model: the toolset is built on the <strong>OpenNomos</strong> platform, where every valid contribution — a new tool, a bug fix, an improvement — earns ecosystem points and benefits. It's infrastructure for <em>computable growth</em>: contribute, use, earn.</p> <p>If you've ever shipped a tiny utility and watched it disappear into the void, this is the opposite of that. Your idea ships directly, and the contribution is attributed.</p> <h2> Try it </h2> <p>Open <a href="https://json.opennomos.com/" rel="noopener noreferrer">json.opennomos.com</a>, convert a timestamp, format some JSON, and if you spot something you'd build better — contribute it. The community grows with what you bring.</p> <p>Clean tools, open contribution, real rewards. That's the whole pitch.</p> webdev opensource showdev productivity
